Abstract: Methods and apparatus for sensor including a die, a leadframe having opposed first and second surfaces, the leadframe supporting the die on the first surface, lead fingers to provide electrical connections to the leadframe and to the die; and a component electrically coupled to the leadframe and to a first one of the lead fingers such that the component is an integrated part of the IC package. The leadframe may have a cutout region in which the component is positioned.

Abstract: Methods and apparatus for a magnetic field sensor in a molded IC package having a magnetic field sensing element in a die with a component coupled to a leadframe at a downset area. In embodiments, a thickness of the leadframe in the downset area is less than a thickness of the leadframe in a non-downset area adjacent to the downset area.

Abstract: Apparatus and methods for detecting passing magnetic articles using a first, True Power On State (TPOS) detector during a first time interval and transitioning to a second, running mode detector after the first time interval, when the output of the second detector is accurate. A phase comparator is responsive to the output signal of the first and second detectors and provides a control signal indicative of a change in the phase relationship between the two output signals. An output switch controlled by the phase comparator provides, as the detector output signal, the first detector output signal during the first time interval and the second detector output signal thereafter.
